"The target is Timmy's seventh birthday," Molly whispered. "What kind of defenses are we looking at?" asked Bill. "Heavy security. There is a bouncy castle blocking the patio, four caffeinated mothers guarding the cupcakes, and a hired clown named Bongo patrolling the perimeter." "Bongo is ruthless. I heard he twists balloon poodles with lethal intent." "Focus. The primary loot is stacked by the gazebo. LEGO Death Stars, drones, and a motorized mini-Ferrari." "Dibs on driving the mini-Ferrari through the pet door!" "You weigh two hundred pounds, Bill! Now, where is your disguise?" "I rented a giant purple dinosaur suit." "That mascot was cancelled in the nineties! The children will smell a setup!" "Children respect apex predators, Molly. While I lure the little monsters into a manic rendition of the hokey-pokey, you slip under the folding table." "And if the birthday boy spots me?" "Bribe him with fun-sized candy. If that fails, weaponize the chocolate fountain." "Understood. Did you grease the wheels on the red wagon?" "Thoroughly. Pure vegetable oil. It rolls silent as a ghost." "Bag the presents, dump them in the cart, and initiate retreat." "Synchronize juice boxes. We breach when the piƱata explodes."
